Communication and Instrumentation Units (CIUs)

September 2020 - Present

• The electrical team on Formula UBC often works in conjunction with other sub

teams in order to log data or improve the efficiency of existing systems. In order

to better record this data, I took on the task of designing a modularized board

that reads analog signals and converts them to digital before sending them to our

datalogger over CAN bus.

• This project will also produce a test board that can be used by any future projects

that also use the STM32F405 microcontroller.

Images of some of the schematics can be found on the following slide.

• A very critical aspect of this project was

the selection of components. In order

for these boards to be versatile and

provide a lasting solution, I used a

weighted decision matrix to help select

between different microcontrollers and

CAN transceivers.

Some images of the STM32

development board used as a

prototype can be found on the

next slide.

• The prototype boards enabled new

members to work with STM32

microcontrollers without having to

worry about designing the

supporting circuitry for the chip. This

means that the prototyping stage of

the design cycle can take much less

time, seeing as members can test

their circuits on a breadboard and

connect them to a programmable

STM.

Home Alarm System Prototype

May 2020 – September 2020

• Over the summer of 2020, I designed

circuitry and programmed an ATmega328P

to function as a home alarm using a

pyroelectric motion sensor. My main

objective with this project was to become

comfortable with interrupt service

routines, microcontroller interfacing with

external devices (like an LCD screen), and

continue to practice writing firmware in

embedded C.

Dash Panel Circuit Board

September 2019 – April 2020

• In my first project on Formula UBC, I was in

charge of designing a dash panel circuit

board in an effort to eliminate wiring clutter

behind the dash and to save weight on the

car. This project introduced me to analog

circuit and printed circuit board design. A

unique aspect of this project was that the

electrical and ergonomic components of

the project were equally important.

Reflow Oven Controller

January 2020 – February 2020

• In my second year project course, I worked in

a group with 5 other students to develop a

reflow oven controller. My role in the project

was to write the firmware for the

microcontroller and ensure that all of the

subsystems functioned well together.

• This project introduced me to embedded

systems, and sparked the passion that I have

today towards firmware development and

circuit design.
